Test automationcronn develops with passion – and for us this includes test-driven development and test automation. Hundreds of software projects for customers of different sizes and industries have provided us with extensive experience in test engineering. Software testing is the only durable and reliable indicator of software quality and enables short and flexible development cycles without compromising on long-term reliability and security.

Test-driven development and the automation of tests make software development more flexible and faster. Since the quality is constantly controlled and guaranteed, fast development cycles, iterations and adjustments are possible no matter how complex the project.
Automated tests are a natural part of software development for us. We limit manual testing to a few areas in which automated testing does not make economic sense. The implementation of automatic tests by cronn is carried out continuously, repeatably and quickly, without the use of additional test personnel.
Test-driven development (TDD) is an important part of cronn’s identity. With TDD we continuously ensure code quality and keep the risk of errors and undesirable side effects low when adapting and changing software. Our experts have testing experience from hundreds of projects.
Our testers have mastered a wide repertoire of methods and tools at different levels of abstraction: unit, regression, integration, system, or end-to-end tests. We work with tools such as: JUnit, Cucumber, Selenium, Cypress, SonarQube and Playwright.
If required, we will work with you to develop test cases and test architectures, implement test environments and ensure automation. We are also experienced at migrating existing tests. Our testers implement sustainable solutions and are always available to further support your business. Upon request, we take over your software testing from A to Z.

Wir arbeiten bereits seit einigen Jahren erfolgreich mit cronn zusammen. Auch in diesem Projekt haben sie unsere Anforderungen schnell verstanden. So konnten wir gemeinsam eine KI-basierte Lösung entwerfen und in Produktion bringen. Wir schätzen cronns Know-how in den Bereichen KI sowie Backend und sind mit der Umsetzung sehr zufrieden.
We lead our customers' software projects to success from our offices in Bonn, Hamburg and Białystok (PL). Always on our side: our dedicated team; our joy in coding; as well as agility, Java, and open-source technologies. We always stay up to date with the latest technologies, tools, and methods.
